blade shape
Hello everybody

Can anyone tell me why shape (geometry) of axial compressor blades are more complex than Steam Turbine blades.

Re: blade shape
(1). I don't think so. (2). The pressure increases along the compressor path, at the same time, the Mach number decreases. So, it is sensitive to flow separation. (3). For turbine blades, the Mach number increases and the pressure decreases. So, relatively speaking, it is less sensitive to the flow separation. (4). Internal flow separation and prediction is still a very difficult subject.
